Given numbers are 731,706,698,872,717
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 731,706,698,872,717 is 56305802144568.
Find LCM of 731,706,698,872,717 with Prime Factorization
| 2 | 731, 706, 698, 872, 717 |
| 731, 353, 349, 436, 717 |
Multiply the prime numbers at the bottom and the left side.
2 x 731 x 353 x 349 x 436 x 717 = 56305802144568
Therefore, the lowest common multiple of 731,706,698,872,717 is 56305802144568.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
731 x 706 x 698 x 872 x 717 = 225223208578272
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
731 : 1, 17, 43, 731
706 : 1, 2, 353, 706
698 : 1, 2, 349, 698
872 : 1, 2, 4, 8, 109, 218, 436, 872
717 : 1, 3, 239, 717
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,706,698,872,717, is 1.
Now, the common factors can be found like this.
731:17x 43
706:2x 353
698:2x 349
872:2x 2x 2x 109
717:3x 239
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 225223208578272/(1x4)
LCM = 225223208578272/4
LCM = 56305802144568
Thus, we can understand that the LCM of 731,706,698,872,717 is 56305802144568.
